GE Lumination Introduces High Power White LEDs

Lumination introduces proprietary, new VIO? High-power white LED, the LED chip has a color shift of less than 100k after 50,000 rated life, and the minimum color shift overcomes many of the inherent color control problems of standard blue or trichromatic LEDs. In addition to this, VIO? LEDs are also highly efficient at warmer color temperatures and have flexible performance (1W or 4W; CRI is 70 or 85; color temperature is 3500K or 4500K, and in late 2007 or 2008) In the early stage, we launched 3000K products).
Using your own blue-violet chip technology, VIO? The high-power white LED combines the 405nm chip with Lumination's own hybrid phosphor, and the phosphor on the hemispherical lens converts violet light into white light. The operating wavelength of the VIO violet chip is higher than that of the blue LED. The color temperature of 3500K or 4100K is suitable for a variety of general lighting standard lamps. VIO LEDs can be avoided by the frequent strobes or bright spots of LEDs in the luminaire and the multiple shadows that can be generated by multiple point sources. The high-power 4W VIO LED emits light more consistently over a 180-degree viewing angle.

Potential applications for white VIO LEDs include general lighting (chandeliers, bracket wall lights), commercial lighting (work lights, displays), landscape lighting (small roads, courtyard lighting), and architectural lighting (washing lights and sign lights). Its color stability is very good and can be used as a replacement for traditional general illumination sources. Other features of the VIO LED are as follows:

70% lumen maintenance rate

Operating life of 50,000 hours at maximum motherboard temperature

Chip-on-board packaging improves thermal management

Simplified, intensive color binning: +/?C 200K one-time classification, +/?C 100K second binning

Plug-and-play connection simplifies manufacturing without the need for soldering. Easy on-board thermocouple measurement points for measurement design verification accuracy

GE-class reliability, electrostatic discharge (ESD) secondary standard

Mercury-free, LED-compliant RoHS directive

Lumination evaluates VIO? High-power white LEDs are an important milestone in the use of GE quality LEDs for general-purpose lighting. Lumination's investment in this major new product underscores its commitment to building global prestige in the general lighting market earlier this year and believes that its violet chip technology provides the most effective control of the color shift of white LEDs. The new product opens up a new century of lighting for OEM manufacturers and designers.
